>>2466786>>Evolution isn’t some gradual process>literally is thoughfunny thing here, naziposter might be referring to puncuated equilibrium which is an entirely legitimate theory in biological evolution where natural selection is not so much a slow shift as it is continual genetic diversification which provides the 'raw material' for relatively brief periods of rapid selection via particularly dramatic mechanisms. now relatively brief still means thousands to tens of thousands of years on a geological and biogical timescale, and dramatic mechanisms of selection would be over a similar timescale. so something like acidification of the oceans over thousands of years selecting for a particular subset of more acid tolerant + ecologically generalist crustaceans out of a far wider population of species that slowly diversified to fill various niches. or something like subsets of small mammals in the mesozoic that adapted a niche in burrowing to compete with/stay safe from dinosaurs, which could have been an effective adaptation in itself which didnt need to change for literally a hundred million years. but in the mesozoic extinction event that burrowing makes them better suited for thousands of years of hostile climate conditions, and when things clear up again theres endless open niches for them to fill in the absense of dinosaurs and you see a massive diversification of mammals in a brief period.
its a perfectly legitimate theory and most evolutionary biologists accept it to at least some extent or another at least as one significant factor, its a consistent and easy way to account for long 'stagnation' in the fossil record followed by brief bursts of change and diversification.
the kicker here tho is that its a naziposter trying to use this as evidence of human racial differences being accountable through natural selection, when the guy who pioneered this theory of punctuated equilibrium was stephen jay gould, who you might know from his extensive writings and debates demonstrating why race science is bullshit and all the attempts to legitimize it have always been bad faith methodogical manipulation. see pdf related
